TUNING
To get the most out of your White Brothers fork, it is important that you tune the fork to fit your
weight, riding style and the terrain you ride.
INITIAL BREAK-IN PERIOD:
Your new fork is designed to break-in over a period of 10 hours or more of riding. As all the parts
bed into each other, the stiction (friction) of the fork decreases and the sensitivity increases. After
the initial brake-in period, fine tuning the air pressure and damping adjustments may be
beneficial to achieve the best possible performance.
TOOLS NEEDED:
Your new White Brothers fork is designed with a air spring and oil damping. The
following guidelines for adjusting and maintaining your fork will enable you to enjoy
maximum performance and longevity from your fork.
1. First, test ride the fork over easy terrain. If after riding the fork over varied terrain you
decide that more tuning is necessary, continue to the next step.
2. The compression or spring of the fork can be changed two ways: 1) by adjusting the
spring air pressure 2)by adjusting the rebound setting or adding air to the damper.
3. To adjust the air pressure remove the dust cap from the left leg to expose the air valve.
Add or remove pressure using a high pressure air pump to achieve your desired spring
support. 50-100psi. is the user range. The fork is delivered with 80 psi.
4. Compression adjustment is done by adding or removing air at the top of the right leg.
Pressures can range from 50 to 150 lbs. Higher air pressure will provide more
compression damping while lower air pressure will provide less compression damping.
Less compression damping will increase the fork dive but will feel smoother over small
bumps. More compression damping will feel stiffer over small bumps but will be more
resistant to bottoming. DO NOT COMPRESS FORK WITHOUT AIR IN DAMPER!
5. Rebound adjustment is done by turning the knob on the bottom of the right leg. Turn
the knob clockwise for slower rebound. To speed up rebound, turn the knob counter-
clockwise. Start with a middle setting and fine tune the rebound from there. Proper
rebound will allow the tire to track the ground over consecutive bumps. Too slow of
rebound will pack-up (feel stiff over consecutive bumps) while rebound set too fast will
cause the fork to top out harshly. Usable adjustment range is 1.5 to 6 turns out from
bottom.
